Abstract: ObjectiveTo investigate the relationship between application of goniscope and Ultrasound Biomicroscope (UBM) and study the assistant methods to improve clinical values of goniscope in the diagnosis of angle-closure glaucoma.Methods22 patients(39 eyes) who had been examined by goniscope and UBM were analyzed.Results32/39 eyes were diagnosed consistently with both methods and 7/39 eyes differently.ConclusionCompared with UBM,goniscope might make a wrong judgement,the ratio was about 18%.Combining with narrow slit of biomicroscope,dynamic observation and indentation,the diagnosis made by goniscope could be more exact.
